TED STATES WILLIAM SONDERGARD, OF SPOKANE, WASHINGTON.

COMPOSITION OF MATTER. TO BE USED BY SHOW-CARD \VRITERS, ARTISTS, AND ARCHITECTS, FOR PEN, BRUSH, AND AIR-BRUSH WORK.

N0 Drawing.

T 0 all whom it may concern Be it known that I, IVILLIAM SONDERGARD, a Canadian subject, and a resident of the city of Spokane, Spokane county, State of lVashington, have invented a new and useful Improvement in a Composition of Matter to be Used by Show-Card lVriters, Artists, and Architects, for Pen, Brush, and Air-Brush \Vork, of which the following is a specification.

I use 1 oz. of striping or lining bronze, which are very finely ground impalpable metallic powders. My reason for using thenir being, that they are ground much finer than other powders.

I add to the bronze oz. of mucilaginous adhesive and 1 oz. of water. "Vhen thor be thinned further with water for pen or air brush work.

A great want has long been and now is felt for a gold and silver watercolor that will cover andlook smooth and that can be used with an air brush.

Specification of Letters Patent.

Patented Nov. 16, 19241 Application filed February 7, 1920. Serial No. 357.034..

There are at present water colors on the market. These are made of-coarser powders than I use. They will not cover with a brush and cannotbe used forair brush work.

My composition is intended to be an improvement over existing makes in that it is made of only the very finest ground powders and a thin mucilaginous adhesive, a combination which allows it to pass through the small air brush and which also makes it cover well and enables the show card writers to use it for either pen or brush work with satisfactory results.

Striping or lining bronzes, these being the very finest ground metallic powders, have been or now are used with a micilaginous adhesive.

hat I claim and desire to secure by Letters Patent of the United States is:

'A composition of finest'ground metallic powders and a mucilaginous adhesive.

In testimony that I claim the foregoing as my invention or improvement, I have signed my name in presence of two witnesses, this 2nd day of February, 1920.

WILLIAMO'SONDERGARD.
